What are examples of autotrophs?
answer
plant, bacteria, some protists
question
What are examples of heterotrophs?

fungi, animals, bacteria, some protist
question
The most instant form of energy is known as ________.
answer
ATP
question
Why is ATP a high energy molecule?
answer
The high energy molecule is because of the strength of the bond between the second and third phosphate groups. When it reacts with water it creates more energy than it takes to break the bond.
